Empirical studies of some auxiliary parameters of 96 Hariana bulls used in a progeny testing programme at two SLA farms viz., Madhuri kund (Mathura) and Babugarh (Gaziabad) in U.P. were undertaken. Period/Batch differences were observed to be statistically highly significant in most of the parameters like AFC, ALC, ATF, TPT, TNC, TSV, TNI, TFC, TCR and AFB. The average fertility of bulls (AFB) was lowest for 1st batch (1965–67) and highest for 12th batch (1984–88). The average number of daughters/bull with completed first lactation records was 9.52 against 99.3 inseminations. The probability of getting a daughter's completed 300 days first lactation record was maximum (0.11) for 6th batch and minimum (0.07) for 8th batch. Age of bulls at first collection was lowest 23.92 months for 4th batch (1970–72) and highest 41.22 months for 11th batch (1980–84). For getting 10 completed first lactation daughter records 104 inseminations were required
